Aromatherapy Perfumer Course

Lesson 1 • History and Evolution of Scent

Traces perfumery from ancient ritual use to modern aromatherapy practice. Establishes cultural and scientific context for all subsequent technical study.

Lesson 2 • How the Olfactory System Works

Explains receptor function, signal transmission, and emotional scent response. Grounds blending decisions in human sensory biology.

Lesson 3 • Core Industry Terminology

Defines essential vocabulary used across formulation, sourcing, and marketing. Enables precise communication with suppliers, clients, and colleagues.

Lesson 1 • Quality Assessment and Sourcing

Teaches GC/MS interpretation, organoleptic testing, and supplier vetting. Equips students to detect adulteration and source traceable, high-quality materials.

Lesson 2 • Botanical Origins of Essential Oils

Maps plant families to their aromatic profiles and extraction regions. Connects botanical identity to expected chemical composition and therapeutic use.

Lesson 3 • Essential Oil Chemistry Fundamentals

Introduces terpenes, esters, aldehydes, phenols, and other key chemical families. Links molecular structure to scent character and safety considerations.

Lesson 1 • Absolutes and Concretes

Defines solvent-extracted absolutes and their role in fine fragrance. Addresses residual solvent concerns and appropriate usage levels.

Lesson 2 • Carrier Oils: Properties and Selection

Examines fatty acid profiles, absorption rates, and skin compatibility of key carriers. Guides selection based on formulation purpose and client skin type.

Lesson 3 • Resins, Balsams, and Oleoresins

Covers natural resinous materials as fixatives and base notes. Demonstrates how resins anchor volatile top notes and extend longevity.

Lesson 1 • Comparative and Blind Evaluation

Applies blind testing and side-by-side comparison to sharpen discrimination skills. Builds objectivity and consistency in sensory assessment.

Lesson 2 • Fragrance Families and Accords

Maps the major fragrance families and teaches recognition of classic accords. Provides a structural framework for categorizing and comparing materials.

Lesson 3 • Top, Middle, and Base Note Theory

Explains evaporation rates and their role in fragrance development over time. Teaches students to evaluate a scent across its full dry-down arc.

Lesson 4 • Building Olfactory Memory

Uses repetitive smelling protocols and scent journaling to encode aromatic references. Establishes the sensory database needed for confident blending.

Lesson 1 • Blending for Therapeutic Intent

Integrates chemical knowledge with therapeutic goals to create purposeful blends. Bridges aromatherapy science and perfumery craft in a single formulation process.

Lesson 2 • Harmony, Contrast, and Balance

Teaches how complementary and contrasting materials create dynamic, balanced blends. Develops aesthetic judgment for evaluating and refining compositions.

Lesson 3 • Dilution Ratios and Safe Usage Levels

Establishes safe concentration ranges for skin, inhalation, and diffusion applications. Prevents sensitization and adverse reactions through precise measurement.

Lesson 4 • Structural Blending Frameworks

Introduces the accord, pyramid, and chord models as compositional scaffolds. Guides students from intuitive mixing to deliberate structural design.

Lesson 1 • Dermal Sensitization and Irritation

Explains the mechanisms of sensitization, irritation, and phototoxicity. Enables risk-based decisions about material selection and usage levels.

Lesson 2 • Product Category Compliance

Applies safety rules to leave-on, rinse-off, and inhalation product categories. Demonstrates how application type changes permissible concentration levels.

Lesson 3 • Allergen Identification and Disclosure

Identifies the most common fragrance allergens and labeling obligations. Ensures transparent communication with consumers and regulatory compliance.

Lesson 4 • Workplace and Storage Safety

Addresses flammability, ventilation, spill management, and proper material storage. Protects the formulator and workspace from chemical hazards.

Lesson 1 • Product Concept and Brief Development

Translates a market idea or client need into a structured formulation brief. Establishes clear objectives before any material selection begins.

Lesson 2 • Formulating Aromatic Skincare Products

Applies dilution and carrier knowledge to serums, balms, and body oils. Integrates therapeutic and aesthetic goals within safe concentration limits.

Lesson 3 • Perfume and Eau de Toilette Creation

Guides construction of alcohol-based fine fragrance at varying concentrations. Covers maceration, filtration, and final sensory evaluation steps.

Lesson 4 • Diffusion and Inhalation Products

Formulates reed diffusers, room sprays, and inhalation blends for ambient use. Addresses evaporation dynamics and safe airborne concentration levels.

Lesson 1 • Complex Accord Construction

Builds multi-material accords that function as unified building blocks. Elevates compositional sophistication beyond simple note layering.

Lesson 2 • Developing a Creative Brief

Translates abstract concepts, emotions, and narratives into olfactory direction. Builds the ideation skills needed for original, concept-driven compositions.

Lesson 3 • Peer Review and Professional Critique

Structures constructive feedback sessions using industry evaluation criteria. Builds resilience and objectivity through guided peer and instructor critique.

Lesson 4 • Modifying and Improving Existing Formulas

Applies systematic modification techniques to elevate draft compositions. Develops critical self-editing skills essential for professional-quality output.
